The Port of Seattle announced today Southwest, Jazz Aviation, and Spirit Airlines received the 2019 Fly Quiet awards, recognizing those airlines doing the best job minimizing noise impacts on local communities for operations at Seattle-Tacoma International Airport in the last calendar year.


Airlines are judged using 3 award criteria: the sound levels of their operations (utilizing four of the Port’s noise monitors); success at flying within the noise abatement flight procedures; and adhering to the airport’s ground maintenance engine run-up regulations.

Southwest Airlines aircraft at Sea-Tac AirportSouthwest Airlines received the Fly Quiet Bravo Award, which goes to the quietest jet airline among the five busiest airlines operationally at Sea-Tac Airport. Southwest Airlines was recognized for noise levels that were consistently lower than competitors and for flying noise abatement procedures at a high rate of success.

Air Canada Express aircraft in flightJazz Aviation, operating as Air Canada Express, received the Fly Quiet Regional Award for operating as the quietest regional jet airline. Jazz Aviation reached remarkably low levels of noise from their operations and had good success flying noise abatement procedures.

Spirit Airlines aircraft in flightSpirit Airlines received the Fly Quiet Award for operating the quietest jet airline with at least 1,000 annual operations. Spirit Airlines reached noise levels that were significantly lower than their competitors in this large group and consistently flew noise abatement procedures correctly.

“We appreciate the efforts and consideration made by our award winners for Fly Quiet, who recognize the importance of reducing impacts to our local communities,” said Lance Lyttle, Managing Director of Sea-Tac Airport. “This is an impressive cross-section of our airlines and we feel it is important to continue to recognize their work that is not always apparent to the public.”

After more than a decade of recognizing airlines with the Fly Quiet Awards, in 2020 the Port of Seattle will add a new “Late Night Noise Limitation” scoring category that will assign air carriers a penalty score for exceeding noise thresholds between midnight and 5 a.m. The Port is developing the broader Late Night Noise Limitation Program and other proposals to reduce aviation noise in consultation with StART (Sea-Tac Airport Stakeholder Advisory Round Table), a stakeholder advisory group made up of local city representatives and aviation leaders.

The Port is currently pursuing three recommendations that originated with StART:

  • a Late Night Noise Limitation Program, which includes voluntary measures to reduce late night (midnight to 5 a.m.) noise by incentivizing air carriers to fly at less noise sensitive hours or transition to quieter aircraft;
  • a new Runway Use Plan agreement between the FAA and the Port, which includes revising the current Runway Use Plan for the FAA to minimize the use of the 3rd Runway during late night hours (midnight to 5 a.m.); and
  • a long term project includes an Instrument Landing System (ILS), a glide slope proposal that would raise Runway 34R’s glideslope for arriving aircraft to potentially reduce noise.

These programs and proposals, along with others that are in development, require ongoing discussion and approvals from airlines and federal aviation officials. Learn more about StART, including detailed agendas, summaries, presentations and to sign up for email alerts.
